Description

Technical Field

[0001] The present invention relates to the technical field of power cables, and specifically to a tractor with anti-impact overload protection. Background Art

[0002] A cable is a device for transmitting electrical energy or signals. It is usually a cable similar to a rope formed by twisting several or several groups of wires. The wires in each group are insulated from each other and are often twisted around a center. The whole is covered with a highly insulating coating. Cables have the characteristics of being electrically conductive inside and insulated outside. There are power cables, control cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, and so on.

[0003] During the erection process of a cable, a tractor is needed. Usually, a take-up roller is used to traction and wind up the cable. When the traditional tractor is in use, it usually directly uses the take-up roller to traction and wind up the cable. However, in the actual traction process, it is very easy to cause the cable traction to have a tension overload. When there is a tension overload, the protection device can give an alarm in time and pause the traction of the cable. However, at this time, the overall tension of the cable is too large and it remains in a tight state continuously, which is easy to cause stress damage. Therefore, in view of the above current situation, there is an urgent need to develop a tractor with anti-impact overload protection to overcome the deficiencies in the current practical applications.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

The cable untying and stress relief component can simultaneously unlock the overload sensing component and the energy release and impact resistance unit. The overload sensing component drives the locked cable to move downward to release the pulling force. At the same time, the partition shield can move back and forth at this time and absorb the impact force. The two cooperate with each other to make the overall tension of the cable smaller, avoid it being continuously in a taut state, and thus cause stress damage, ensuring the service life of the cable and the safety during traction. Through the setting of the overload protection unit, cooperating with the double-end limiting unit and the energy release and impact resistance unit, this application can accurately position the cable during the cable traction process, ensure the stability of the cable during traction, enable the device to be applicable to cables of different sizes, and can also automatically lock the cable when it is overloaded, and make the pulling force be quickly released by unlocking the overload sensing component and the energy release and impact resistance unit, so that the overall tension of the cable becomes smaller, avoiding it being continuously in a taut state and thus causing stress damage.

[0037] Please refer to Figure 1 and Figure 2, in an embodiment of the present invention, a tractor for impact overload protection includes: a maintenance table 1; a partition shield 2, which is fixedly connected to the outer side of the top of the maintenance table 1, and wire threading ports 3 are provided on both side shield walls; a traction winding unit 4, which is arranged outside one wire threading port 3 and is fixedly connected to the partition shield 2 for realizing the traction and winding of the cable; a double-end limiting unit 6, which is symmetrically arranged inside the partition shield 2, is respectively connected to the two wire threading ports 3 and is fixedly connected to the partition shield 2 for cooperating with the partition shield 2 to realize the guiding and positioning of the cable; an overload protection unit 7, which is arranged between the two double-end limiting units 6 and is connected to the partition shield 2 for cooperating with the double-end limiting unit 6 to support the cable and complete the locking and energy release of the overloaded cable; an energy release and impact resistance unit 5, which is arranged outside the bottom end of the partition shield 2, is connected to the partition shield 2 and is also connected to the overload protection unit 7 for cooperating with the overload protection unit 7 to absorb the impact force generated when the cable is overloaded; wherein, the overload protection unit 7 includes: an overload sensing component 8, a quantitative triggering component 9 and a cable-untying and relief component 10. The overload sensing component 8 is arranged between the two double-end limiting units 6, is slidably connected to the partition shield 2 and is connected to the cable-untying and relief component 10 arranged on the partition shield 2 for cooperating with the cable-untying and relief component 10 and the double-end limiting unit 6 to support the cable and monitor the tensile force. Inside the overload sensing component 8, there is a quantitative triggering component 9 connected to the cable-untying and relief component 10 for cooperating with the overload sensing component 8 to lock the overloaded cable and synchronously drive the cable-untying and relief component 10 to untie the overload sensing component 8 and complete the energy release of the overloaded cable. The cable-untying and relief component 10 is also connected to the energy release and impact resistance unit 5 for cooperating with the quantitative triggering component 9 to synchronously unlock the energy release and impact resistance unit 5 and complete the absorption of the impact force generated when the cable is overloaded.

[0038] In this embodiment, when the device is running, the cable passes through the wire threading port 3 on one side and the double-end limiting unit 6, then passes through the overload sensing component 8, and then passes out through the wire threading port 3 on the other side and the double-end limiting unit 6, and is connected to the traction winding unit 4. The double-end limiting unit 6 can accurately position the cable, ensuring the stability of the cable during traction. When the pulling force is overloaded, the cable drives the quantitative triggering component 9 through the overload sensing component 8. The quantitative triggering component 9 can cooperate with the overload sensing component 8 to lock the cable. At the same time, the quantitative triggering component 9 can drive the cable unlocking and buffering component 10, and the cable unlocking and buffering component 10 can simultaneously unlock the overload sensing component 8 and the energy release and impact resistance unit 5. The overload sensing component 8 drives the locked cable to move downward to release the pulling force. At the same time, the partition shield 2 can move back and forth at this time and absorb the impact force. The two cooperate with each other to make the overall tension of the cable smaller, avoid it being continuously in a taut state, and thus cause stress damage, ensuring the service life of the cable and the safety during traction. In this application, by setting the overload protection unit 7, cooperating with the double-end limiting unit 6 and the energy release and impact resistance unit 5, the cable can be accurately positioned during cable traction, ensuring the stability of the cable during traction, enabling the device to be applicable to cables of different sizes, and can also automatically lock the cable when it is overloaded, and by unlocking the overload sensing component 8 and the energy release and impact resistance unit 5, the pulling force can be quickly released, so that the overall tension of the cable becomes smaller, avoiding it being continuously in a taut state, and thus causing stress damage.

[0039] In one embodiment of the present invention, please refer to Figure 2 、 Figure 3 and Figure 4 , the overload sensing component 8 includes: a mounting seat 11, a support frame 12, a sliding column 13, a fixed column 14 and a trigger 15. The mounting seat 11 is arranged between the double-end limiting units 6 on both sides, is slidably connected to the partition shield 2, abuts against the cable unlocking and buffering component 10 at the bottom end, and a support frame 12 connected to the cable is slidably connected to the inner side of the top end.

When the tensile force is overloaded, the cable drives the support frame 12 to move towards the trigger 15. When the critical value is reached, the bottom end of the support frame 12 contacts the trigger 15, and the trigger 15 is used to drive the quantitative trigger assembly 9. The quantitative trigger assembly 9 can not only cooperate with the support frame 12 to lock the cable, but also drive the release and relief assembly 10. The release and relief assembly 10, on the one hand, releases the lock on the mounting seat 11, and on the other hand, releases the lock on the energy release and impact resistance unit 5. At this time, the mounting seat 11 slides down along the connection groove, so that the tension of the cable is released. At the same time, the unlocked energy release and impact resistance unit 5 can absorb the impact force, thereby ensuring the safety of the equipment when the cable is overloaded. By providing the overload sensing assembly 8, the state of the cable can be detected in real time.
